AURORA – A Parker man is accused of attacking his former mental health worker with a hammer and fracturing her skull, claiming if he scared her that he would get back “energy” he says she stole from him.

The alleged attack happened around 6:30 p.m. on Nov. 18 in the 4100 block of S. Dunkirk Way in Aurora, according to a probable cause statement for the arrest of 45-year-old Filipp Kazakov.

Police were called out on a report of a home invasion robbery and found the victim, a woman, covered in blood at her neighbor’s house with a huge gash on her forehead, according to the probable cause statement.

She told police that she had also suffered a broken arm in the attack and had passed out. The woman told police she knew her attacker was a man named Filipp before she was taken to an area hospital, where doctors confirmed she had a broken humerus bone in her arm and “multiple penetrating skull fractures,” among other injuries.

Denver Sheriff Patrick Firman's resignation this week culminated years of mistrust from deputies and community activists, who said that was the price of filling the position with a man who was never the right person for the job.
